I purchased a tour because I was traveling alone and was not confident in navigating the city on a tight schedule. It was the best decision I made for this trip. The guide was so full of information at each stop we made and incredibly knowledgeable. If you are going to Istanbul I would highly recommend this tour and ask for the guide by the name of "Tibet" She was excellent! I felt safe, comfortable and learned so much about this beautiful part of Istanbul. What an incredible value --to have my own private tour guide!
